Re: Standard Horizon DS-1 depth finder
New display modules are still available, around $50-60 IIRC from Signet. But it sounds like you have a moisture issue. I'd remove it and open it up, let it dry out and have a look around. Once it's dry and there's no obvious issues ('burnt' smell, corrosion, etc) try it again.
When the displays fail they usually bleed out 'black' obscuring the characters.
We have the same stuff on our boat.. nearly indestructable. Ebay and Craigslists are another venue for replacement.
